Transaction management system and method

A transaction processing method is provided for a transaction management system which processes transactions using settlement cards. In the transaction processing method, a transaction process is executed based on individual control information that is input at each transaction and transaction information for the transaction. A judgment is made based on the transaction information whether or not the transaction satisfies at least one count-up condition indicating a predetermined range of transaction types. When the transaction meets the count-up condition, numerical information indicative of the number of transactions satisfying the count-up conditions is added. A determination is made whether or not a numerical value represented by the numerical information after the addition is within a range specified by extraction conditions. Individual control information corresponding to the added numerical information determined to be within the range is extracted; and card holder information corresponding to the extracted individual control information is outputted.
